TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed December 8, 1917. Serial No. 206,181.

To all whom it may concern:

Be it known that I, VVAnn S. IRELAND, a citizen ofthe United States ofAmerica, a resident of the city of St. Louis, State of Missouri, haveinvented certain new and useful Improvements in Type-Writing Machines,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to improvements in typewriting machines. Prior tothis invention typewriting machines, especially shorthand machines, havebeen provided with means for feeding a continuous strip of paper whichusually unwinds from. a roll and passes to a printing device, wherebythe characters are printed line by line. Owing to the peculiarrequirements of a shorthand machine, .it is a decided advantage to use avery long strip of paper so that the writing or printing. may becontinued for a long period of time without frequent interruptions.However, considerable difiiculty has been experienced in handling thelong strip of paper after it passes from the printing elements.

The .main object of my invention is to produce a very simple means forcutting the paper into relatively short sections. The preferred form ofthe invention includes a cutting device under the control of a cuttingkey. This cutting key is independent of the printing keys, and it may beactuated at irregular inter'va'ls to ,cut the paper into nonuniformsections, For example, at the end of a letter or other dictationrelating to some particular subject. the cutting key may be operated tosever the paper. y' using the cutting key in this manner, the long stripof paper can be divided into irregular sections, each provided withprinted matter relating to some particular subject. The relatively shortsect-ions can be easily han died, and they maybe conveniently filed forfuture reference.

In the structure I have'shown, the paper advances, step by step inresponse to movements of the printing keys, and the paper is also fed bythe cutting key. When the cutting key is actuated, the paper advances tolocate the last line of printed matter at a point beyond the cuttingelements, and one of said cutting elements then moves across the path ofthe paper. By feeding the paper immediately before the cuttingoperation, all of the printed matter will appear on the severed sheet ofpaper.

Figure I is a side elevation of a shorthand machine constructed inaccordance with my invention, a portion of one of the side walls beingbroken away to show the means for actuating the cutting device, alsoshowing the means for feeding the pa per immediately before the cuttingoperation.

Fig. II is a plan view, partly in section, of the rear portion of themachine.

Fig. III is a transverse sex-tion taken approximately on the lineIIIIII, Fig. IV.

Fig. IV is a longitudinal section of the machine.

Fig. V is a detail view of the paper feeding roll.

Fig. VI is a section taken approximately on the line VI-VI, Fig. V,showing the clutch through which movement is transmitted from theprinting keys to the paper feeding roll.

Fig. VII is a section on line VIIVII, Fig. V, showing the retainingclutch associated with the paper feeding roll to prevent retrogrademovement.

To illustrate the invention. I have shown a shorthand machine providedwith printing keys 1 secured to key levers 2, the latter being pivotallysupported by a pivot rod 3 (Fig. IV). Each key lever 2 is provided atits rear end with an upwardly extending printing hammer 4L adapted tocooperate with a type bar 5 having type characters 6 on its bottom face.An inking ribbon 7 passes between the type 6 and the printing hammers 4.Each key lever is arranged directly below a restoring spring 8 (Fig.IV), and the restoring springs yieldingly hold the key levers in theirnon-printing positions. The. strip of paper 9 (Figs. I and IV) passesfrom a supply roll 1.0, under a rod 11, thence upwardly and over a paperfeeding roll 12, downwardly through an inclined passageway 13, and thenrearwardly to a cutting device near the rear of the machine. The papertravels between the printing hammers 4 and the inking ribbon 7 before itreaches the cutting device. When a printing key is depressed, its keylever 2 turns about the axis of the pivot rod 3 (Fig. IV) and theprinting hammer 4 at the rear of the key lever moves upwardly to force aportion of the paper onto the inking ribbon 7, at the same time forcingthe ribbon onto one of the type characters 6. The printing keys may beoperated independently df each other to print selected characters, andseveral keys may be operated simultaneously to. print a line ofcharacters, as is well understood in this art. The characters areusually printed line by line, a complete word or syllable beingprinted-during each key operation, the strip of paper is advanced onestep in response to each key operation.

The paper feeding device comprises a universal bar 14 (Fig. IV) arrangedover the key levers at a point in front of the rinting hammers 4 andfixedto a bell crank ever 15, the latter being pivotally supported bythe pivot rod 3. The upwardly extending arm of this bell crank lever 15is notched to receive a pin 16 (Figs. IV,V and VI) projecting from theoscillatory drive member 17 of a :paper feeding clutch. This drivemember 17 is loosely mounted in a driven clutch member 18, the latterbeing secured to one end of the paper feeding roll 12. The drive member17 oscillates freely in response to the movements of the universal barso as to impart a step by step movement to the paper feeding roll. Whenthe oscillatory drive member 17 turns in the direction indicated by thearrow in Fig. VI, the small spring pressed rollers 19 are freely clampedin the tapering or wedge-shaped spaces between said drive member and thedriven clutch member 18. Movement is then transmitted from the universalbar, through the drive member 17 and rollers 19, to the driven clutchmember 18. The paper feeding roll is secured to the driven clutch member18 (Fig. V) so as to advance one step when the oscillatory drive member17 turns in the direction indicated by the arrow in Fig. VI. During thereverse movement, when the drive member 17 moves oppositely to thedirection indicated by the arrow in Fig. VI, the small rollers 19 tendto move away from the points of the tapering spaces, and they do nottransmit movement to the .driven clutch member 18. In response to theoscillatory movements of the universal bar and the drive clutch member17, the paper feeding roll 12 turns continually, step by step in thedirection indicated by the arrow in Fig. VI.

the rotary clutch member 18'; These small rollers 19 allow the feedrollto turn freely in the direction indicated by the arrows in Figs. VI andVII, but if an effort is made to reverse the direction of movement, the

small rollers 19', by tending to move toward the points of thewedge-shaped spaces, will cooperate with the stationary clutch member 17to prevent such retrograde movement.

To illustrate the preferred form of the invention, I have shown acutting device including blades 26 and 27 (Figs. II, III and IV) locatedat points on opposite sides of the path of the paper, and adapted tosever the paper after it passes from the printing device. The blade 26is closely fitted to an arcuate seat on an oscillatory blade holder 28.This arcuate blade 26 is secured to the blade holder 28, as shown mostclearly in Fig. IV. When the blade holder 28 moves downwardly from theposition shown in Fig. IV, the blades 26 and 27 cooperate with eachother to sever the paper.

The blade 27 is referably secured to an arm 31 (Fig. IV) the latterbeing pivoted at 32. A spring 33, connected to the arm 31, tends toforce the blade 27 into the path of the arcuate blade 26. When the blade26 occupies the elevated position shown in Figs. III and IV, anextension 26', extending downwardly from the blade 26, ,is engaged Imounted in suitable bearings, and an operating arm 37 is rigidly securedto the journal 36. A restoring arm 38 (Figs. I and III) extendingdownwardly from the journal 36, is connected to a restoring spring 39which normally retains said arm 38 in engagement with an abutment 40,thereby yieldingly retaining the oscillatory blade holder 28 in itselevated position.

' 41 designates a cutting key (Figs. I and II) in the form of a bellcrank lever, pivotally supported at 42, and connected by means of. alink 43, to the operating arm 37. This operating arm is provided with apin 44 which lies in a slot 45 at one end of the link 43. A' spring46,secured to the link 43,

tends to retain said link and the cutting key in the positions shown inFig. I. It will now be understood that the cutting key 41 may beactuated to drive the operating arm 37,

thereby turning the journal 36 so as to actuate theoscillatory bladeholder 28. The operating arm 37 and blade holder 28 are both rigidlysecured to the journal 36..

The paper feeding roll 12 is secured to a shaft 47 provided with aratchet Wheel 48 which lies adjacent to the link 43 (Fig. I).

A pawl 49, pivoted to the link 43, is normally held in engagement with apin 50 (Fig. I) by means of a spring 51. This spring is attached to thelink 43 and also to the pawl 49. The point of the pawl lies near theratchet wheel 48.

It will now be understood that the printing keys'can be actuated toprint selected characters line by line, and to feed the paper step bystep from the printing device to the cutting device. The printing keysare free to move independently of the cutting key 41, so as to printupon and feed the paper continuously, without actuating "the cuttingdevice. The ratchet wheel 48 (Fig. I) turns, step by step, with thepaper feeding roll 12, but this does not in any way affect the cuttingdevice.

The cutting elements 26 and 27 are located near the path of the paper ata point beyond the printing device as shown in Fig. IV, and the lastline of printed matter lies very close to the printing device. Severallines of printed matter are normally located between the printing deviceand the cutting elements. Therefore, the strip of paper should beadvanced. or fed, immediately before the cutting device is actuated,otherwise the severed sheet of paper would not include all of theprinted matter.

hen the cuttin key is depressed, the paper is automaticailyfed therequired distance to locate all of the printed matter beyond the cuttingelements, and the blade 26 then moves across the path of the paper. Atthe beginning of .the downward movement of the cutting key (Fig. I) thepawl 49 cooperates with the ratchet wheel 48 to turn the paper feedingroll 12, thereby advancing the paper. At this time the slot 45, in therear end of link 43, allows the link and cutting key to moveindependently of the cutting elements. Thereafter, the point of the pawl49 passes from the ratchet wheel 48, and a continued downward movementof the cutting key will cause the cutter-operating arm 37 (Fig. I) tomove. to the position shown by dotted lines. The paper feeding device isthus actuated independently ofthe printing keys to feed the last fewlines of printed matter through the space between the cutting elements,and thereafter, while the paper is at rest, the cutter is actuated tosever the printed matter from the blank portion of the strip. All ofthis is preferably accomplished by a single stroke of the cutting key.

The paper feeding device actuated by the printing keys is claimed in anapplication for patent filed by me on May 19, 1917, Serial Number169,621. The paper straightening device comprising the rod 11 combinedwith a paper feeding device as herein shown, is claimed in anapplication for patent filed by me on May 19, 1917, Serial Number169,620.
